This advisory circular (AC) provides information to assist in determining whether government or government-contracted aircraft operations conducted within the territory of the United States are public or civil aircraft operations under the statutory definition of "public aircraft," in Title 49 of the United States Code (49 U.S.C.) §§ 40102(a)(41) and 40125 (the statute). Additionally, this AC contains Federal Aviation Administration (FAA) policy pertaining to civil aircraft operators that provide contract support to government entities. The intent of this material is to better define the responsibilities of the parties to these contracts. This AC is not mandatory and does not constitute a regulation. Nothing in this AC changes the legal requirement for public aircraft operators to comply with the statute.

Atmospheric Turbulence Avoidance
This Advisory Circular (AC) describes to pilots, aircrew members, dispatchers, and other operations personnel the various types of clear air turbulence (CAT) and some of the weather patterns associated with it. Also included are “Rules of Thumb” for avoiding or minimizing CAT encounters. Appendix 1 provides a sample Atmospheric Hazards Advisory and Avoidance System that air carriers can tailor to their specific needs.

FAA Quality Control System Certification Program
This circular describes the Federal Aviation Administration (FAA) Quality Control System Certification Program and the mechanics of implementation. It is intended for guidance and information only.

Status of Federal Aviation Regulations
This circular provides the public with the current publication status of the looseleaf Federal Aviation Regulations, prices, and order form. This Advisory Circular
will be updated later this year because of the frequent changes.

This advisory circular (AC) describes the Federal Aviation Administration (FAA) Aviation Safety Reporting Program (ASRP) which utilizes the National Aeronautics and Space Administration (NASA) as a third party to receive and process Aviation Safety Reports. This cooperative safety reporting program invites pilots, controllers, Flight Attendants (F/A), maintenance personnel, dispatchers, and other users of the National Airspace System (NAS), or any other person, to report to NASA actual or potential discrepancies and deficiencies involving the safety of aviation operations. The operations covered by the program include departure, en route, approach, and landing operations and procedures; air traffic control (ATC) procedures and equipment; crew and ATC communications; aircraft cabin operations; aircraft movement on the airport; near midair collisions (NMAC); aircraft maintenance and recordkeeping; and airport conditions or services. The effectiveness of this program in improving safety depends on the free, unrestricted flow of information from the users of the NAS. Based on information obtained from this program, the FAA will take corrective action as necessary to remedy defects or deficiencies in the NAS. The reports may also provide data for improving the current system and planning for a future system.

Pilot Windshear Guide
Communicates key windshear information relevant to flight crews. Appendix 1 of this advisory circular is the Pilot Windshear Guide, which is only one section of the two-volume Windshear Training Aid.

AFS-300

Voluntary Industry Distributor Accreditation Program
Describes a system for the voluntary accreditation of civil aircraft parts distributors on the basis of voluntary industry oversight and provides information that may be used for developing accreditation programs. The FAA believes such programs will assist in alleviating lack of documentation and will improve traceability.

AND-720

Hazardous Mountain Winds and Their Visual Indicators
Assists pilots involved in aviation operations to diagnose the potential for severe wind events in the vicinity of mountainous areas. It provides information on preflight planning techniques and on in-flight evaluation strategies for avoiding destructive turbulence and loss of aircraft control. Pilots, dispatchers, air traffic controllers, and other who must deal with weather phenomena and the routing of aircraft will benefit from the information contained in this advisory circular.

Provides information for aircraft operators from the United States who plan to conduct specialty air services (SAS) operations in Canada or Mexico in accordance with the North American Free Trade Agreement. It also provides information for aircraft operators from Canada or Mexico who plan to conduct SAS operations in the U.S.

Event Planning Guide
Describes acceptable methods for organizing the aviation community for all events, such as major sports events (auto racing, golf, etc.) It is not limited to sporting events, but can be used whenever there is a large amount of aviation activity on an infrequent basis and open gatherings of people. The goal of this AC is to enhance air and ground safety. This AC does not include events that require FAA Form, 7711-1, Application for Certificate of Waiver or Authorization.

a. Flight Information Services (FIS). FIS is a service that provides Meteorological Information (METI) and Aeronautical Information (AI) to enhance pilot awareness of weather and/or airspace constraints while providing information for decision support tools and improving safety. METI and AI data link services enable flightcrews to support the Next Generation Air Transportation System (NextGen) concepts of information sharing and provide airmen with a common operating picture necessary to support the evolving global Air Traffic Management (ATM) concepts.

b. Advantages of FIS METI and AI. FIS of METI and AI can augment pilot voice communications with Flight Service Stations (FSS), other air traffic control (ATC) facilities, airline dispatch centers, flight following facilities or other Operation Control Centers (OCC), typically referred to as System Operations Control (SOC). In addition, Internet connectivity provides the capability for Baseline Synchronization Services (BSS) to be utilized to update the aircraft’s navigational and other databases prior to flight.
